    Amazing 120hz VRR OLED display, the best on the market. The camera is something I didn't know I'd use that much, but it has turned out to be very useful. This is obviously a phone that is well past the point of diminishing returns for bang for your buck. But chances are, you won't care.

    Love this phone, i wish i couldve gotten the nice cameras on a smaller device because the screen is definetly very big but regardless, i am so happy i made the decision on the ultra instead of the regular s21 or 21+

    Love love love this phone. If anybody buys this phone PLEASE make sure it works! I bought my first one 6 days before this one and after 2 days realized that when I got or made calls I couldn't hear anybody so I had to return it. For the amount of money you pay it should work perfectly the first time. But my second one I absolutely love and it works perfect. Still trying to figure out all the ins and outs of it but so far I absolutely love it and it was definitely worth the money!!! I've NEVER spent this much on a phone in my life but I finally spent a little money on myself and am happy I did!!!

    My Aunt and I were both in need of new phones! I use mine for work so I wanted something that didn't need an upgrade a few months later! It works great and you can take the best pictures ever!

    Great phone...holds charge 3 days and is a good all around phone. Im not a fan of Apple so this is my preffered choice. I have otterbox on it and it works very well at keeping it safe

    Very nice phone with a sleek design. I’m still getting used to it (iPhone user). I love using the notes app in this phone vs the one on iPhones. The camera quality is awesome to say the least.

    I bought the phone for the camera and to be able to use the S Pen. It has really good screen and as bright as you want it. As I said I bought it for the camera and I'm still learning how to use it.

    This is the best Android phone have ever owned. Samsung have outdone themselves once again with this year's top-tier S Ultra series! The 6.8" 1440p 120hz OLED display is beautiful to behold.

    Wait for pixel 6 if you take pictures at night

    This is a great phone, big screen, big battery, coming from a pixel 4xl there are few things I miss though. The phone won't screen your calls for you and it doesn't have the hold feature where the phone holds for you if your on a call and get put on hold. Also if you like getting quick operating system updates this isn't the phone for you, The battery life is better than the pixel but the camera is inferior if you take pictures with little light. The pixel night sight camera feature still can't be beat. All in all I probably would have been happier waiting for the pixel 6 pro, but I wanted to a phone I could use a stylus with.
